Wearing jail oranges, handcuffs and shackles, Murray made an initial court appearance Friday as formal charges were filed, one day following the homicide.

"Justice needs to be quick…the manner is which he committed the crime is horrifying and justice needs to be served," District Attorney Richard Smothermon said. "It was a random, senseless murder just to gratify the defendant."

The East Central University student is being held in the Pottawatomie County Public Safety Center; his next court date is scheduled Jan. 8.

Murray is accused in the shooting death of Generro Sanchez, 18, who also was student at ECU in Ada. Both the suspect and victim were freshmen and reportedly lived in the dorms on campus.

Murray is accused of offering Sanchez $20 to take him on a trip to Walmart, but instead forced him at gunpoint to drive to an area about five miles north of Asher, where arrest affidavit alleges Murray shot and killed his classmate and left is body in the ditch.

Murray allegedly admitted to investigators that he'd been planning to kill someone for the past three weeks, according to the arrest affidavit, and targeted Sanchez, who he only knew by his first name.

The victim's body was found in a ditch along Substation Road, which is located south of U.S. 177 and SH 59.

Asher police reported some type of suspicious activity in that area and it was about 2:34 a.m. Thursday when Deputy Justin Abbott called Undersheriff Travis Palmer about the discovery of the body, later identified as Sanchez.

As Palmer was responding, he heard radio traffic about a possible suspect seen walking north on U.S. 177.

Palmer located Murray near Sing Road and asked him if he had a gun.

Murray said, "No sir, it's in the truck and I am the guy you're after," the arrest affidavit reads.

Palmer asked Murray why deputies would be looking for him.

Murray responded with, "Cause of the guy I shot and put in the ditch on Substation Road," according to the affidavit.

The affidavit shows Murray admitted that he made a plan to kill someone about three weeks ago but didn't know who he'd kill or when, but knew he would do it around Substation Road because he knew that area.

According to the interview, Murray allegedly used a .40-caliber firearm that was stolen from a house in Asher.

Murray allegedly told investigators that he shot Sanchez twice before he "rolled the victim down into a ditch," where he covered him up with leaves and sticks, the affidavit alleges.

As he covered the body, a car approached the area and the driver stopped. Murray allegedly told that passerby that he had fallen asleep and then asked for a ride to his grandmother's home in Asher, the document shows.

The passerby apparently took Murray to Asher, then it is believed that Murray was allegedly walking northbound on U.S. 177 back to the crime scene when Palmer found him walking, Booth said.

During his interview, Palmer asked Murray, who said he had no remorse of the killing, what he thought a person should get for killing someone.

The arrest affidavit shows Murray said, "Death — an eye for an eye."

Smothermon said while the death penalty is being considered, it's still too early to make that decision in this case.

Sanchez is reported to be from Stuart, Okla.

While the crime happened away from the ECU campus, it is also affecting the student body there so counselors are ready to assist students.
